From b97eaaf594a297cbca3d44407d8b8ca333cc5377 Mon Sep 17 00:00:00 2001 From: Dread <34528298+islandbitcoin@users.noreply.github.com> Date: Fri, 17 Oct 2025 19:31:03 -0400 Subject: [PATCH 01/12] feat: Implement referral system with Email/SMS/WhatsApp invites Add comprehensive invite-friend feature allowing users to invite friends via Email, SMS, or WhatsApp. **User-Facing Features:** - Create invites: Users can send invites via Email (SendGrid), SMS, or WhatsApp (Twilio) - Redeem invites: New users can redeem invites within 1 hour of account creation - Preview invites: Unauthenticated endpoint to preview invite before registration - Rate limiting: 10 invites/day per user, 3 invites/day per target contact (Redis-based) - 24-hour invite expiration with Firebase Dynamic Links support **Admin Features:** - View invite details with inviter/redeemer information - List and filter invites by status and inviter - Paginated invite queries **Technical Implementation:** - MongoDB schema for invite tracking with secure token hashing (SHA-256) - Notification service supporting Email, SMS, and WhatsApp - Contact validation for email/phone formats - Deep linking support via Firebase Dynamic Links - Comprehensive test coverage (unit & integration tests) **Security:** - Tokens are 40-character random strings with only SHA-256 hash stored - Contact verification ensures invite sent to correct recipient - Account age validation (< 1 hour) for new user redemption - Self-redemption prevention --- dev/apollo-federation/supergraph.graphql | 68 +++++ dev/bin/gen-test-jwt.ts | 51 +++- src/app/admin/index.ts | 4 + src/app/admin/invite.ts | 179 ++++++++++++ src/app/invite/index.ts | 111 ++++++++ src/app/invite/invite-repository.ts | 59 ++++ src/app/invite/queries.ts | 107 +++++++ src/app/invite/rate-limits.ts | 22 ++ src/app/invite/redeem-invite.ts | 60 ++++ src/config/env.ts | 14 + src/config/index.ts | 4 + src/config/yaml.ts | 13 + src/domain/invite/index.ts | 26 ++ src/domain/invite/validation.ts | 33 +++ src/domain/rate-limit/errors.ts | 2 + src/domain/rate-limit/index.ts | 16 ++ src/graphql/admin/queries.ts | 4 + src/graphql/admin/root/query/invite-by-id.ts | 22 ++ src/graphql/admin/root/query/invites-list.ts | 66 +++++ .../admin/types/object/admin-invite.ts | 46 ++++ .../admin/types/object/invites-connection.ts | 9 + src/graphql/public/mutations.ts | 5 + src/graphql/public/queries.ts | 2 + .../public/root/mutation/create-invite.ts | 260 ++++++++++++++++++ .../public/root/mutation/redeem-invite.ts | 165 +++++++++++ .../public/root/query/invite-preview.ts | 90 ++++++ src/graphql/public/schema.graphql | 52 ++++ src/graphql/public/schema/invite.graphql | 45 +++ .../shared/types/scalar/invite-method.ts | 13 + .../shared/types/scalar/invite-status.ts | 14 + src/graphql/shared/types/scalar/timestamp.ts | 19 +- src/services/mongoose/accounts.ts | 2 + src/services/mongoose/models/invite.ts | 87 ++++++ src/services/notification/index.ts | 219 +++++++++++++++ src/services/notifications/invite.ts | 107 +++++++ src/utils/hash.ts | 19 ++ src/utils/index.ts | 1 + tsconfig.json | 1 + 38 files changed, 2006 insertions(+), 11 deletions(-) create mode 100644 src/app/admin/invite.ts create mode 100644 src/app/invite/index.ts create mode 100644 src/app/invite/invite-repository.ts create mode 100644 src/app/invite/queries.ts create mode 100644 src/app/invite/rate-limits.ts create mode 100644 src/app/invite/redeem-invite.ts create mode 100644 src/domain/invite/index.ts create mode 100644 src/domain/invite/validation.ts create mode 100644 src/graphql/admin/root/query/invite-by-id.ts create mode 100644 src/graphql/admin/root/query/invites-list.ts create mode 100644 src/graphql/admin/types/object/admin-invite.ts create mode 100644 src/graphql/admin/types/object/invites-connection.ts create mode 100644 src/graphql/public/root/mutation/create-invite.ts create mode 100644 src/graphql/public/root/mutation/redeem-invite.ts create mode 100644 src/graphql/public/root/query/invite-preview.ts create mode 100644 src/graphql/public/schema/invite.graphql create mode 100644 src/graphql/shared/types/scalar/invite-method.ts create mode 100644 src/graphql/shared/types/scalar/invite-status.ts create mode 100644 src/services/mongoose/models/invite.ts create mode 100644 src/services/notification/index.ts create mode 100644 src/services/notifications/invite.ts create mode 100644 src/utils/hash.ts diff --git a/dev/apollo-federation/supergraph.graphql b/dev/apollo-federation/supergraph.graphql index 9c8d30139..075dcbf6d 100644 --- a/dev/apollo-federation/supergraph.graphql +++ b/dev/apollo-federation/supergraph.graphql @@ -961,6 +961,20 @@ type Country scalar CountryCode @join__type(graph: PUBLIC) +input CreateInviteInput + @join__type(graph: PUBLIC) +{ + contact: String!

12:14:40 -0700 Subject: [PATCH 07/12] feat(invite): tiered referral reward payout on Bridge KYC approval Implements the referral reward the invite feature only stubbed. When an invited user's Bridge KYC is approved (they gain a US account), both the inviter and the invitee are paid a tiered USD reward, funded from a dedicated 'rewards' wallet. - New 'rewards' account role (AccountRoles, mongoose enum, AdminRole); assign it to the funding account via a direct mongo write. Resolved with AccountsRepository().findByRole. - Tiered amount by global referral sequence (atomic counter): 1-100 -> $5, 101-600 -> $2.50, 601+ -> $1. Ops-tunable via the new referralReward config block (default DISABLED, so nothing pays until a rewards wallet is assigned). - Trigger: the once-only pending->approved transition in the Bridge KYC webhook (CAS-guarded). Payout via intraledgerPaymentSendWalletIdForUsdWallet. - Idempotent + fail-closed: atomic claim on the invite, per-party inviter/inviteeRewardedAt, never double-pays; a failed/partial payout is recorded (rewardStatus) for manual reconciliation and never throws into or blocks KYC approval. Admin visibility via new AdminInvite reward fields. Tests: 23 unit (9 tier boundaries + 14 payout paths incl. idempotency, partial, failed, disabled). tsc-check clean; admin SDL regenerated. (Also fixes a latent tsc-check type error in the admin invite spec's mock.)

Subject: [PATCH 08/12] fix(invite): make the feature CI-green (scope-map, lint, module-load) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The invite feature was never CI-green (never merged), so PR #462 surfaced several gaps plus two regressions from the reward payout: - api-key scope-map: register createInvite (authed mutation) as BLOCKED so the deny-by-default completeness test passes. redeemInvite/invitePreview are in the unauthed schema block, so they are (correctly) not authed root fields. - award-referral-reward: lazy-import send-intraledger inside payParty so merely importing @app/invite no longer pulls the IBEX client (baseLogger.child at init) — was breaking kyc.spec + create-invite.spec at module load. - ops-events-hooks.spec @config mock: add getInviteCreateAttemptLimits/ getInviteTargetAttemptLimits (domain/rate-limit evaluates them at load). - prettier/eslint: format the never-linted invite files; drop unused imports (InviteToken; redeem-invite mutation dead imports); type two anys in services/notification. Gates: eslint 0 errors, tsc-check + tsc-check-noimplicitany clean, full unit suite 1304 passed / 0 failed.

Stuck-claim recovery: the atomic claim stamps rewardClaimedAt, and any unexpected throw after the claim downgrades it to 'failed' with a rewardError instead of stranding an invisible 'processing' row. - IBEX Pending is a distinct non-terminal 'pending' rewardStatus (new enum value). Per-party timestamps are still set for pending parties — fail-closed, a re-run can never double-pay — but ops now sees it needs re-checking instead of it being counted as terminally paid. - Payouts fund from the rewards account's USDT wallet first (the active cash wallet), falling back to USD, and recipients are resolved strictly in the funding wallet's currency (send-intraledger rejects cross-currency sends). - Tier fail-safe: a schedule missing its unbounded sentinel pays 0 past the last bound instead of silently over-paying forever. Tests: award spec 14->18 (post-claim throw, pending semantics, wallet preference/currency-match, claim stamp), tier fail-safe boundaries. Gates: scoped jest 130/130, tsc-check + noimplicitany + eslint clean.

F2: the post-claim catch preserves payment evidence — a throw mid-payout now records partial with the paid party's timestamp instead of failed-with-nothing (manual reconciliation can no longer double-pay a paid party). F3: redeemInvite moved to the authed block + scope-map BLOCKED (was reachable by read-scoped API keys via the unauthed shield gap). SDL unchanged. F4: raw invite tokens and Twilio auth-token fragments no longer logged. F5: revoked/EXPIRED-status invites rejected at redeem + preview, independent of the date check. F6: Timestamp scalar accepts ISO strings again (parseInt regression silently turned admin cutover scheduledAt into 1970); pure digits = epoch seconds, invalid input errors. Pinned by a new scalar spec. F7: admin invitesList — ObjectId cast for the pipeline filter (was always empty) and validated _id-cursor pagination (was parseInt(after,16) nonsense). F8: a failed invite notification deletes the invite and returns an error instead of burning the contact's 24h dup-window with nothing sent. F9: dead app-layer redeem module deleted; the LIVE resolver now has a 14-case spec (token/window/phone/EMAIL/self/race/revoked/success paths). Full unit suite 157 suites / 1326 passed / 0 failed; tsc-check, noimplicitany, eslint clean.
